We determined whether or not the extent of drug interaction of fexofenadine by itraconazole is time-dependent.
In a randomized two-phase crossover study, itraconazole was administered orally for 6 days, and, on days 1, 3 and 6, fexofenadine was administered simultaneously. On another occasion, fexofenadine was administered alone.
Itraconazole increased fexofenadine AUC(0, infinity), and the % change for difference was 178% (95% CI 1235, 3379), 205% (95% CI 1539, 3319) and 169% (95% CI 1128, 2987) on days 1, 3 and 6 of the 6 day treatment, respectively.
The extent of drug interaction by itraconazole was not time-dependent.
我们确定了伊曲康唑与非索非那定的药物相互作用程度是否具有时间依赖性。
在一项随机两阶段交叉研究中,口服伊曲康唑6天,在第1、3和6天同时给予非索非那定。在另一个时间段,单独给予非索非那定。
伊曲康唑增加了非索非那定的AUC(0,∞),在6天治疗的第1、3和6天,差异的百分比变化分别为178%(95%可信区间1235,3379)、205%(95%可信区间1539,3319)和169%(95%可信区间1128,2987)。
伊曲康唑的药物相互作用程度不具有时间依赖性。
